System for Determining Allocation of Tape Drive Resources for a Secure Data Erase Process

a tape drive and resource allocation technology, applied in the field of automatic data storage systems, can solve the problems of inability to distinguish between physical and virtual volumes, physical and virtual drives, and long-expired physical volumes which may contain sensitive data, and achieve the effect of improving the significance of how data is “deleted” or disposed of, improving the performance of secure data erase, and improving the security of data eras

Benefits of technology

[0014]The significance of how data is “deleted” or disposed of has increased as confidential data has begun to play a more vital role in business transactions and stricter regulations are imposed on maintaining customer privacy. To protect confidential or sensitive data (e.g., credit card information, social security number) and to maintain customer privacy it is advantageous to perform a secure data erase on certain data so that it is unrecoverable after a certain time interval (e.g. a grace period), through any reasonable means. Accordingly, one...

Problems solved by technology

The host cannot distinguish between physical and virtual volumes, or physical and virtual drives.
One issue of VTS systems is the management of data within the tapes.
The VTS system may have a number of duplicate...

Embodiment Construction

[0024]The following is intended to provide a detailed description of an example of the invention and should not be taken to be limiting of the invention itself. Rather, any number of variations may fall within the scope of the invention which is defined in the claims following the description.

[0025]The present disclosure allows for a method to ensure a timely secure data erase by giving priority for secure data erase to the physical volumes closest to their secure data erase deadline. Moreover, in one embodiment, the present disclosure ensures timely secure data erase by allocating more tape drive devices to aid in the secure data erase process when it is determined that the current allocation will not be able to meet the secure data erase demand. Finally, in a further embodiment, the present disclosure provides a process to return to a minimum allocation of tape drives when the minimum allocation of tape drives will be able to meet the secure data erase demand.

Abstract

A system is provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application is related to U.S. patent application Ser. No. 11 / ______ (Docket No. TUC9-2006-0217US1), “Method for Determining Allocation of Tape Drive Resources for a Secure Data Erase Process,” filed concurrently herewith, and naming Kishi et al. as inventors.TECHNICAL FIELD[0002]The disclosure relates generally to automated data storage systems and more particularly, to a system and for selectively performing a secure data erase.BACKGROUND OF THE INVENTION[0003]A virtual tape system is a tape management system such as a special storage device or group of devices and software which manages data such that the data appears to be stored entirely on tape cartridges when portions of the data may actually be located in faster, hard disk storage. Programming for a virtual tape system is sometimes referred to as virtual tape server (VTS), although these terms may be used interchangeably, unless otherwise specifically indicated. A virtu...
